WINDOW 3 'Sheets-Sheet 2 Filed March 7, 1947 INVENTOR Lu//'en Hee/en ATTORNEYS 3 3| preferably by means of split pins 40 passed through suitable registering apertures formed in the end plate 3| and retaining plate 35. The opposite end of the roller is formed with a hollow axial recess 4I in which a helical spring 42 is disposed. 'Ihe spring has its outer end secured to the roller and its inner end attached to or made an integral part of a rod 38 which extends through the spring and has a Vpintle 43 formed at its outer end which is rotatably mounted within the end of the roller, as shown in Fig. 1l.

This pintle is of polygonal shape andV is non-rotatably carried by a similarly shaped aperture formed in the plate 32, whereby the pintle, and therefore the attached end of the spring, will be prevented from rotating as the screen is unwound from the roller by the raising of the window sash. The spring is so wound that the opening of the window causes its tension to be increased, whereby the screen will be kept stretched taut across the window opening at all times.

The casing 24 is also provided with an inner depending attaching flange 44 formed with two or more inverted keyhole slots 45, whereby the flange may be passed over the heads of attaching screws 46 carried by the sash rail, and then forced downwardly so as to bring the screw bodies in :drm engagement with the upwardly extending parallel sides of the upper portions of the slots, whereby the casing unit will be firmly secured to butl easily detachable from the sash rail. The top wall of the casing is formed at each end with recesses 50 and 5I for the free passage'of the casing over the parting beads I5. and the runners or closing anges 52, respectively, to be hereinafter described. The top Wall 25 where each of the recesses 50 and 5I is formed is provided with a depending reinforcing flange 53 and 54, respectively.

The roller 28 for the upper sash II is substantially identical to that described for the lower sash. The casing unit 23 is also of similar formation but disposed in inverted position as shown in Fig. 4. It is preferably secured in position to the sash rail of the upper sash in detachable manner as hereinbefore described in connection with the casing of the lower sash. A'suitable tension spring (not shown) is also provided for and mounted within the screen roller 28 for keeping .ik

the screen I6 stretched taut across the opening when the upper sash is lowered.

Av combined stationary weather strip and runner unit 55 is provided at each side of the Window frame for engagement with each of the sashes II and I2. As clearly shown in the drawings, and particularly in Figs. 3, 6, and 8, each of these units is formed of resilient sheet metal and is secured to one side of t'he parting bead I5. Each unit is formed with a runner portion 52 and a weather strip portion 56.k Each runner portion 52 extends away from the parting strip I5 to a point where its free edge overlaps the free vertical edge of the screen I6, thereby closing the space between the screen and the parting strip so as to exclude flies and insects, Each unit is located within the runway of the window frame and a portion 62 thereof extends a limited distance across the runway where it terminates in the weather strip portion 56. This portion of the unit is formed in a vertically arranged tubular member which is disposed within and resiliently engages the surfaces of a vertical groove formed in each vertical edge of the sash. To seal this unit a felt strip 6I isdisposed Lunder the lateral portion 62 of the unit and between it and the window frame I0.

While any suitable type of sash balance may be employed with sashes embodying my invention, I provide a convenient sash balance in the form of a helical spring 63 disposed in each of the tubular weather strip portions 56 of the unit. One end of each of the springs used in the lower sash I2 is secured to the window sill 22 and the other end is mounted in a cap 64 secured by means of a rivet 65 to a plate 66 carried by the meeting rail of the sash. The counterbalance springs 63 of the lower sash I2 are under compression when .the sash is in closed position whereby the sash will be counterbalanced, The springs 63 for the f upper sash perform their counterbalancing functions under tension when the upper sash is lowered. In order to keep the springs 63 in alignment and in registration with the tubular member of the weather strip portion 56 when being compressed, it is desirable to provide a spring guide lywhic'h extends axially within the springs 63, having its upper, endsecured to the upper end of the spring and to the cap preferably by means of a rivet 'I I.

A suitable weather strip 12 is provided on and between the meeting rails 13 and 14 of the upper and lower sashes, rrespective1y, as clearly shown in Figs. 4 vand 8. So as to close the opening between these meeting rails when the windows are in open positions, I provide a closing flange 15 secured to the lower-surface of the meeting rail 13 and extending toward the window pane 16, and a closing flange secured to the upper surface of the meeting flange 14 and extending therefrom toward the windowpane 8 I.

My invention also contemplates the provision of weather stripping 82 located in the lower edge of the sash railof the lower sash and the upper edge of the Asash rail ofthe upper sash. This weather stripping is shownV enlarged in Fig.` 10.

It comprises two members 83 and 84 made of sheet metalV of iiexblefnature The member 83 is disposed within a suitable groove 85 formed in the rail and., is secured in place by suitable fastening means passing through a centrally arranged recess portion 86 in which is npreferably mounted a striprof felt 90,by which the member is sealed to the sash rail. The member 83 is formed with two Mwings .9I which are bent inwardly and then outwardly thereby forming a throat 9 I. The edges of the wings extend to the outer edges of the recess 85where they are suitably secured. The other member 84 is of inverted U-shape having indentedsides 92 for resilientengagement with the throat 9I of the stationary member 83. The free ends93 of this member extend inwardly toward veach other and normally bear against the lateral walls 94 of the memberSS. YBy this formation the member 84 will be retained within the member 83by means ofthe Vthroat arrangement, but will be free to be collapsed within the latter member when Vengaging the window sill as the window is brought to its closed position. Due to this throat arrangement the member 84 is preferably assembled withinV the member 83 by longitudinalmovement before the sashis assembled within the window frame. Obviously, the bottom curved wall 9-5 of the member 84 extends beyond the lower surface of the sash rail so that it may be collapsed upon contact with the'window sill.

Obviously, some modiiications of the details herein shown and. described may be made without departing. from the spirit of my invention or the scope of the appended claims; and I do not,

therefore, Wish to be limited to the specific details herein shown and described, the form shown being merely a preferred embodiment of my invention.
